TSARI MAI GUDUN GUDU A CIKIN FUEL INJECTOR NOZZLES (Kashi na 1)

Atomization na man fetur yana da mahimmanci wajen sarrafa konewa a cikin injin allura kai tsaye. Sarrafa konewa yana taimakawa wajen rage hayaki da haɓaka aiki. Cavitation yana ɗaya daga cikin abubuwan da ke tasiri sosai ga yanayin fesa a cikin ɗakin konewa. Hannun nozzles na man fetur na yau da kullun kanana ne kuma suna aiki a matsanancin matsin lamba, wanda ke iyakance nazarin halayen bututun mai na ciki. Lokaci da tsayin ma'auni suna ƙara iyakance binciken gwaji na bututun mai injector. Simulating cavitation a cikin man fetur injector zai taimaka a fahimtar sabon abu da kuma zai taimaka a ci gaba da ci gaba.

Gina kowane siminti na cavitating injector nozzles yana farawa tare da ainihin zato waɗanda za a haɗa abubuwan mamaki kuma waɗanda za a yi watsi da su. Har ya zuwa yau, babu wata yarjejeniya game da ko an yarda a ɗauka cewa ƙananan nozzles masu saurin cavitating suna cikin ma'auni na thermal ko inertial.

Wannan bambancin ra'ayi yana haifar da hanyoyi daban-daban na yin samfuri. Idan mutum ya ɗauka cewa bututun ƙarfe yana cikin ma'auni na thermal, to tabbas babu wani babban jinkiri Vi a cikin haɓakar kumfa ko rushewa saboda canjin zafi. Canja wurin zafi yana da sauri mara iyaka kuma tasirin inertial yana iyakance canjin lokaci.

Zaton ma'aunin inertial yana nufin cewa matakan biyu suna da saurin zamewa mara kyau. A madadin, akan matakin ma'auni na ƙananan grid, mutum na iya yin la'akari da yiwuwar ƙananan kumfa waɗanda girmansu ke amsa canje-canje a matsa lamba. Schmidt et al.
